No need to, you can feel it and see. Idea behind that is to favour consumers by
taking advantage of others sites loading same library as yours. So that cache
hit is statistically favoured by the library popularity. When that happen UA
will not make a request at all. The request time is much greater than a cached
load library time so thats all that really matters.
That said, also there is the value of making easier version load and saving you
from the need to maintain that cacheable content in your server.

I saw the code is made like that to take advantage of one style per component.
But, as recently asked and Phillipe said, that is a convenient hack which is
actually useful but not really intended for production. As I dont use #style in
my app's components, I find that convenience actually inconvenient.
